Short summary

The distribution of ozone (O₃) and its precursors (NO_x, VOCs) is explored using the chemistry–climate model MUSICAv0 and evaluated using measurements from the Michigan–Ontario Ozone Source Experiment. A custom grid of ~7 km was created over Michigan. A sector-based diurnal cycle for anthropogenic nitric oxide was included in the model. This work shows that grid resolution plays a more important role in relation to O₃ precursors and that the diurnal cycle significantly impacts nighttime O₃ formation.
